Fillers.

[Acey]

Read up some topics n types of fillers on wizd forum but I don't get the slightest idea yet. I cant find bondo here, so I bought a can of putty filler to experiment. What type of filler resemble bondo? I'm lookin for something that sticks to both metal n plastic, sand-able with hand (i dont have a mouse sander), paint-able, and wont crack. HELP~~~ :eek: I've seen what acrylic filler blablabla on hardware stores but dont know which is appropriate.

You just need an autobody filler, more specifically a plastic expoxy based autobody filler.

I just wrote a bondo guide on my site if your interested. Link in my sig.

Cheers for that tybrenis I was looking for a good bondo tut.

[tybrenis]

Happy I could help.

I read the tut. Its not bad but you should have added more information on the types of bondo. Some bondo is plastic epoxy and some is actual fibreglass in various strand lengths. The epoxy should be used as filler and for small drill holes. The stranded fiberglass should be used if you're going to fabricate a piece (like an air scoop for example) or if you need to cover big holes.

Just to clear things up.

Bondo is a Company name, not the product name.
the Bondo corp, makes Fillers, Expoy resin, polyseter resin, fiberglass products, and many other autobody tools/ products.

Given that the slang term "bondo" here in the USA mainly refers to there plastic body filler not the fiberglass products.
In fact bondo make 3-5 diffrent type of body filler alone.


An other note to add to the tut. Bondo also makes a product called glazing putty (Only get in the auto section, the stuff in the window area from TAP is totaly diffrent and only good for holding window panes in)

Glazing putty is a one part paste, about the consistancy of tootpaste. It is used to fill in small lows and pin holes. Pin holes are air (or gases) bubbles that become trapped in the body filler while it dries. As you sand you remove the material that is bove the bubble and you leave the bottom bowl shape. These are small (the size of a pin prick to about 1/16" in Dia) They are very hard to fill with body puddy bacause it's so thick. This is where the glazing putty comes in you apply a little bit to the item and smooth out with your plastic spreader, leave it a little thick as it shrinks as it dries. The glazing putty sands super smooth bacause the "grains" in it are much smaller so you can "glaze" the whole surface with it if you need a super smooth finish, but don't apply more then 1/32-1/16" at a time or you'll get cracks this is because the glazing putty shrinks allot more then the body filler when it dries.

I've also seen glazing putty called spot putty (spot filler), same thing diffrent company works the same way. They both come in big (6-8" long) metal tubes (again think toothpaste) and are sold in automotive stores, and department stores (wal-mart) world wide.

Glazing putty has the same nasty chemicals in it that body filler has so use the same saftey precautions, Latex ( or similar) gloves, Reperator, safety glasses, and old clothes.


Good Luck,

Note to add:

Bondo have several trading names in other countries. I've googled them all for UK shops without success. It would appear that there are no Bondo products avaliable in the UK. This could be due to our COSHH laws.

Yes, Bondo is simply a plastic autobody filler.

I didn't go too far in depth with this article as I figured most people give their cases paintjobs don't need fiberglass reinforced bondo, as it is very hard to sand down etc.

Glazing putty is some good stuff. I commonly using when painting things. Keep in mind the guide I wrote is not a painting but rather an autobody filler guide.

A case painting guide is coming to a town near you soon.

I wonder if I can add some water colour paste to the putty filler I bought... without mixing water to it, to get some colours.

[tybrenis]

Not a bad idea, but why would you really need to do that? Usually Bondo is prep-work for paint.

[Acey]

Im not gonna paint it. Im using putty filler for the next mod and it's like light flesh coloured. So plan to add a lil brown+orange to the putty so no painting are required (my paint job's always a wreck and cant afford airbrush kit for now). After that just get a layer of clear coat over the whole thing. I think that'll do.

Use the coloring paste and _not_ the liquid drops and it should color up fine... (the same stuff used to color cake icing)

[Acey]

Liquid drops would just screw the putty up cos its written "If filler hardens, just add water"... dang
